8. Draw the graphical representation of Classification AI model. Explain in brief.
Prepared by: M. S. KumarSwamy, TGT(Maths)
Page - 23 -
Classification: The classification Model works on the labelled data. For example, we have 3 coins of
different denomination which are labelled according to their weight then the model would look for
the labelled features for predicting the output. This model works on discrete dataset which means the
data need not be continuous.
OR
In classification, data is categorized under different labels according to some parameters given in
input and then the labels are predicted for the data.
9. Draw the graphical representation of Regression AI model. Explain in brief.
Regression: These models work on continuous data to predict the output based on patterns. For
example, if you wish to predict your next salary, then you would put in the data of your previous
salary, any increments, etc., and would train the model. Here, the data which has been fed to the
machine is continuous.
OR
Regression is the process of finding a model for distinguishing the data into continuous real values
instead of using discrete values. It can also identify the distribution movement depending on the
historical data.
10. Draw the graphical representation of Clustering AI model. Explain in brief.
Clustering: It refers to the unsupervised learning algorithm which can cluster the unknown data
according to the patterns or trends identified out of it. The patterns observed might be the ones which
are known to the developer or it might even come up with some unique patterns out of it.
OR
Clustering is the task of dividing the data points into a number of groups such that data points in the
same groups are more similar to other data points in the same group and dissimilar to the data points

in other groups. It is basically a collection of objects on the basis of similarity and dissimilarity
between them.
11. Explain Data Exploration stage.
In this stage of project cycle, we try to interpret some useful information out of the data we have
acquired. For this purpose, we need to explore the data and try to put it uniformly for a better
understanding. This stage deals with validating or verification of the collected data and to analyze
that:

than one job at the same time.





OR
Neural Networks have the ability to learn by themselves and produce the output that is not
limited to the input provided to them.
The input is stored in its own networks instead of a database; hence the loss of data does not
affect its working.
These networks can learn from examples and apply them when a similar event arises, making
them able to work through real-time events.
Even if a neuron is not responding or a piece of information is missing, the network can detect
the fault and still produce the output.
They can perform multiple tasks in parallel without affecting the system performance

future generations more organized and sustainable. This process may lead to better lives for mankind.
14. What are the different types of sources of data from where we can collect reliable and
authentic datasets? Explain in brief.
Data can be a piece of information or facts and statistics collected together for reference or analysis.
Whenever we want an AI project to be able to predict an output, we need to train it first using data
There could be many ways and sources from where we can collect reliable and authentic datasets
namely Surveys, Web scrapping, Sensors, Cameras, Observations, Research, Investigation, API etc.
Sometimes Internet is also used to acquire data but the most important point to keep in mind is that
the data should be taken from reliable and authentic websites only. Some reliable data sources are
UN, Google scholar, Finance, CIA, Data.gov etc.
QUESTIONS AND ANSWERS (SET 01) - 3/4 marks
1. Explain the AI Project Cycle in detail.
The steps involved in AI project cycle are as given:
 The first step is Scope the Problem by which, you set the goal for your AI project by stating
the problem which you wish to solve with it. Under problem scoping, we look at various
parameters which affect the problem we wish to solve so that the picture becomes clearer
 Next step is to acquire data which will become the base of your project as it will help you in
understanding what the parameters that are related to problem scoping.
 Next, you go for data acquisition by collecting data from various reliable and authentic
sources. Since the data you collect would be in large quantities, you can try to give it a visual
image of different types of representations like graphs, databases, flow charts, maps, etc. This
makes it easier for you to interpret the patterns in which your acquired data follows.
 After exploring the patterns, you can decide upon the type of model you would build to
achieve the goal. For this, you can research online and select various models which give a
suitable output.
 You can test the selected models and figure out which is the most efficient one.
 The most efficient model is now the base of your AI project and you can develop your
algorithm around it.
 Once the modelling is complete, you now need to test your model on some newly fetched
data. The results will help you in evaluating your model and hence improving it.
Finally, after evaluation, the project cycle is now complete and what you get is your AI project.
2. Explain the relation between data size and model performance of an Artificial Neural
Network.
The basis for any kind of AI development is BIG DATASET. The performance of any AI based
application depends on the data supplied
ANN models are also known as Learning models and are used for prediction purposes. These are
mostly developed without paying much cognizance to the size of datasets that can produce models of
high accuracy and better generalization. Although, the general belief is that, large dataset is needed to
construct a predictive learning model. To describe a data set as large in size, perhaps, is circumstance
dependent, thus, what constitutes a dataset to be considered as being big or small is somehow vague.

In fact, the quantity of data partitioned for the purpose of training must be of good representation of
the entire sets and sufficient enough to span through the input space. It must be authentic and relevant
to give better model performance.
3. Draw the 4Ws problem canvas and explain each one of them briefly.
The 4Ws problem canvas is the basic template while scoping a problem and using this canvas, the
picture becomes clearer while we are working to solve it.
a) Who: The “Who” block helps you in analyzing the people getting affected directly or indirectly
due to it? Under this, you find out who the ‘stakeholders’ to this problem are and what you know
about them. Stakeholders are the people who face this problem and would be benefitted with the
solution.
b) What: Under the “What” block, you need to look into what you have on hand. At this stage, you
need to determine the nature of the problem. What is the problem and how do you know that it is a
problem?
c) Where: In this block, you need to focus on the context/situation/location of the problem. It will
help you look into the situation in which the problem arises, the context of it, and the locations where
it is prominent.
d) Why: in the “Why” canvas, think about the benefits which the stakeholders would get from the
solution and how would it benefit them as well as the society.
4. Differentiate between rule-based and learning-based AI modelling approaches.
Rule Based Approach: It refers to the AI modelling where the relationship or patterns in data are
defined by the developer. The machine follows the rules or instructions mentioned by the developer,
and performs its task accordingly.
For example, suppose you have a dataset comprising of 100 images of apples and 100 images of
bananas. To train your machine, you feed this data into the machine and label each image as either
apple or banana. Now if you test the machine with the image of an apple, it will compare the image
with the trained data and according to the labels of trained images, it will identify the test image as an
apple. This is known as Rule based approach. The rules given to the machine in this example are the
labels given to the machine for each image in the training dataset.
Learning Based Approach: In this approach, the machine learns by itself. It refers to the AI modelling
where the relationship or patterns in data are not defined by the developer. In this approach, random
data is fed to the machine and it is left on the machine to figure out patterns and trends out of it.
Generally, this approach is followed when the data is un labelled and too random for a human to
make sense out of it.
For example, suppose you have a dataset of 1000 images of random stray dogs of your area. You
would put this into a learning approach-based AI machine and the machine would come up with
various patterns it has observed in the features of these 1000 images which you might not have even
thought of!
5. What is an Artificial Neural Network? Explain the layers in an artificial neural network.
Artificial Neural Network: Modeled in accordance with the human brain, a Neural Network was built
to mimic the functionality of a human brain. The human brain is a neural network made up of
multiple neurons, similarly, an Artificial Neural Network (ANN) is made up of multiple perceptrons.
A neural network consists of three important layers:
Input Layer: As the name suggests, this layer accepts all the inputs provided by the programmer.
Hidden Layer: Between the input and the output layer is a set of layers known as Hidden layers. In
this layer, computations are performed which result in the output. There can be any number of hidden
layers
Output Layer: The inputs go through a series of transformations via the hidden layer which finally
results in the output that is delivered via this layer.
6. What is the need of an AI Project Cycle? Explain.
Prepared by: M. S. KumarSwamy, TGT(Maths)
Page - 27 -
Project cycle is the process of planning, organizing, coordinating, and finally developing a project
effectively throughout its phases, from planning through execution then completion and review to
achieve pre-defined objectives.
Our mind makes up plans for every task which we have to accomplish which is why things become
clearer in our mind. Similarly, if we have to develop an AI project, the AI Project Cycle provides us
with an appropriate framework which can lead us towards the goal.
The major role of AI Project Cycle is to distribute the development of AI project in various stages so
that the development becomes easier, clearly understandable and the steps / stages should become
more specific to efficiently get the best possible output. It mainly has 5 ordered stages which
distribute the entire development in specific and clear steps: These are Problem Scoping, Data
Acquisition, Data Exploration, Modelling and Evaluation.
7. Explain the following:
a. Supervised Learning b. Unsupervised Learning
Supervised learning is an approach to creating artificial intelligence (AI), where the program is
given labelled input data and the expected output results.
OR
Supervised learning is a learning in which we teach or train the machine using data which is well
labelled that means some data is already tagged with the correct answer. After that, the machine is
provided with a new set of examples (data) so that supervised learning algorithm analyses the training
data (set of training examples) and produces a correct outcome from labelled data.
OR
In a supervised learning model, the dataset which is fed to the machine is labelled. It means some data
is already tagged with the correct answer. In other words, we can say that the dataset is known to the
person who is training the machine only then he/she is able to label the data.
Unsupervised Learning: An unsupervised learning model works on unlabeled dataset. This means
that the data which is fed to the machine is random and there is a possibility that the person who is
training the model does not have any information regarding it. The unsupervised learning models are
used to identify relationships, patterns and trends out of the data which is fed into it. It helps the user
in understanding what the data is about and what are the major features identified by the machine in
it.
OR
Unsupervised learning is the training of a machine using information that is neither classified nor
labelled and allowing the algorithm to act on that information without guidance. Here the task of the
machine is to group unsorted information according to similarities, patterns and differences without
any prior training of data.
8. Differentiate between classification and clustering algorithms with the help of suitable
examples.
Classification is a process of finding a function which helps in dividing the dataset into classes based
on different parameters. In Classification, a computer program is trained on the training dataset and
based on that training; it categorizes the data into different classes. The task of the classification
algorithm is to find the mapping function to map the input(x) to the discrete output(y).
Example: The best example to understand the Classification problem is Email Spam Detection. The
model is trained on the basis of millions of emails on different parameters, and whenever it receives a
new email, it identifies whether the email is spam or not. If the email is spam, then it is moved to the
Spam folder.
Regression is a process of finding the correlations between dependent and independent variables. It
helps in predicting the continuous variables such as prediction of Market Trends, prediction of House
prices, etc. The task of the Regression algorithm is to find the mapping function to map the input
variable(x) to the continuous output variable(y).

Example: Suppose we want to do weather forecasting, so for this, we will use the Regression
algorithm. In weather prediction, the model is trained on the past data, and once the training is
completed, it can easily predict the weather for future days.
OR
Classification is the process of finding or discovering a model (function) which helps in separating
the data into multiple categorical classes. In classification, the group membership of the problem is
identified, which means the data is categorized under different labels according to some parameters
and then the labels are predicted for the data.
Regression is the process of finding a model or function for distinguishing the data into continuous
real values instead of using classes. Mathematically, with a regression problem, one is trying to find
the function approximation with the minimum error deviation. In regression, the data numeric
dependency is predicted to distinguish it. The Regression analysis is the statistical model which is
used to predict the numeric data instead of labels. It can also identify the distribution movement
depending on the available data or historic data.
OR
Key Differences between Classification and Regression
 The Classification process models a function through which the data is predicted in discrete
class labels. On the other hand, regression is the process of creating a model which predicts
continuous quantity.
 The classification algorithms involve decision tree, logistic regression, etc. In contrast,
regression tree (e.g. Random forest) and linear regression are the examples of regression
algorithms.
 Classification predicts unordered data while regression predicts ordered data.
 Regression can be evaluated using root mean square error. On the contrary, classification is
evaluated by measuring accuracy.

10. Do ethics in AI hamper data acquisition stage? Justify your answer.
Data acquisition is the most important factor or stage as the entire project development is based on
the acquired data. There are several ethical issues which must always be considered when planning
any type of data collection.
We need to understand that the data which is collected is ethical only if the provider agrees to
provide. For example, in case of smartphone users, data is collected by clicking on allow when it asks
for permission and by agreeing to all the terms and conditions. But at the same time if one does not
want to share his/her data with anyone then this ethical issue hampers the acquisition process and
lowers the accuracy or amount of data required for development.
Hence Regardless of the type of data collection, it is absolutely necessary to gain the approval of the
community from which the data will collected otherwise.

interests that the project’s results might influence. Project managers, project sponsors, executives,
clients, or users are typically included in this group.
8. What is a confusion matrix? What is it used for?
Answer – The comparison between the prediction and reality’s outcomes is stored in the confusion
matrix. We can determine variables like recall, precision, and F1 score, which are used to assess an
AI model’s performance, from the confusion matrix.
9. What do you mean by Problem Statement Template?
Answer – An stakeholders can define and describe a problem by writing a summarize report called a
problem statement. Its objective is to offer a comprehensive plan of action to address the issue and
include suggestions for how those responsible can stop it from happening again in the future.
10. What is data Acquisition?
Answer – The process of gathering correct and trustworthy data to work with is known as data
acquisition. The second stage of the project cycle is data acquisition, and for successful decision
making, we must make sure the data is gathered from genuine and trustworthy sources.
11. What is the difference between Training Data & Testing Data?
Answer – The datasets are divided into two groups in machine learning. The first subset, referred to
as the training data, is a section of our actual dataset that is used to train a machine learning model.
Second subset, referred to testing data, Once your machine learning model is built, you need unseen
data to test your model. This data is called testing data.
Note – Training data use 80% of the whole data and testing data use 20%.
12. What is data features?
Answer – Data features refer to the type of data you want to collect.

13. What are the various ways to collect data?
Answer – Various ways to collect the data is –
a. Surveys
b. Web Scraping
c. Sensors
d. Cameras
e. Observations
f. Application Program Interface (API)
14. What is data exploration?
Answer – Data exploration is the process of displaying and detecting unique patterns and trends in
data using tools and procedures. Data visualization and other complex statistical techniques can be
used to do this.
15. What is data modelling?
Answer – Data modelling is the process of developing a visual representation of an entire
information system or certain components of it. for example the development, training, and
application of machine learning algorithms that simulate logical decision-making based on accessible
facts are known as AI modelling.
16. What are the types of AI Modelling?
Answer – AI Models are classified into two type –
a. Learning Based
b. Rule Based
17. What is Rule Based Approach?
Answer – When the developer sets the rules. The machine executes its duty in accordance with the
rules or instructions specified by the developer.
A rule-based artificial intelligence (AI) system is one that aims to develop artificial intelligence (AI)
by using a model that is exclusively based on predetermined rules.
18. What is Learning Based Approach?
Answer – AI modelling where the computer learns on its own. The AI model is trained on the data
provided to it under the Learning Based technique, and after that, it is able to create a model that is
flexible to the change in data.
19. What are the different type of Learning based approach?
Answer – The learning based approach can be divided into three types –
a. Supervised Learning – In order for a computer to learn from data, it must have external
supervision. This is known as supervised learning. We use the labelled dataset to train the supervised
learning models. Supervised machine learning is a method for addressing two major issues:
regression and classification.
b. Unsupervised Learning – This term refers to a sort of machine learning in which the machine can
learn from the data on its own without any external supervision. The unlabelled dataset can be used to
train the unsupervised models. These are employed in order to address the Association and Clustering
issues.
c. Reinforcement Learning – Reinforcement learning is a learning process where an agent interacts
with its environment by taking actions and learns through feedback. The agent receives feedback in
the form of rewards; for example, he receives a positive reward for each good activity and a negative
reward for each bad action. The agent is not under any oversight. Reinforcement learning makes use
of the Q-Learning algorithm.

20. Who many type of Supervised Learning models in AI?
Answer – There are two types of Supervised Learning model –
a. Classification – When the data is labeled-based categorized. For instance, under the grading
system, students are categorized based on the grades they receive in relation to their exam marks.
b. Regression – Such models work on continuous data. For example, if you wish to predict your next
salary,
then you would put in the data of your previous salary, any increments, etc., and would train the
model.
21. How many type of Unsupervised Learning model in AI?
Answer – There are two type of Unsupervised learning models in AI –
a. Clustering – refers to the unsupervised learning technique that can cluster the unknown data
according to patterns or trends found in it. The developer may already be aware of the patterns
noticed, or it may even generate some original patterns as a result.
b. Dimensionality Reduction – If you have a large number of features, it could be beneficial to
minimise them using an unsupervised step before moving on to supervised steps. Numerous
unsupervised learning techniques include a transform technique that can be used to lessen the
dimensionality.
22. What is Expert System?
Answer – An expert system in artificial intelligence is a computer programme that mimics the
capacity for judgement of a human expert. Expert systems are created to reason through knowledge
bases that are primarily represented as if-then rules rather than through traditional procedural code.
23. What is the use of computer vision in AI?
Answer – Computers may be taught to understand and extract data from the visual environment, such
as photographs, using an area of artificial intelligence called computer vision. Thus, computer vision
makes use of AI technology to resolve challenging issues like image processing and object detection.
